OBSERVATION-GLASS.

Specification of Letters Patent.

Patented Nov. 30, 1915.

Application filed June 15, 1910. Serial No. 567,112.

T 0 all whom it may concern:

Be it known that I, HARRY H. STYLL, a citizen of the United States, anda resident of Southbridge. in the county of \Vorcester and State ofMassachusetts, have invented certain new and useful Improvements inObservation-Glasses, of which the following is a specification.

Hy invention relates to improvements in observation glasses for takingobservations from behind a screen or barrier and consists in providingmeans for mounting an optical instrument on the barrier whereby saidinstrument may be universally adjustable.

The objects of my improvements are: First, to provide a bearing allowingobservations to be made in all directions; second, to provide means forseating and unseating the instrument in the bearings; third, to providemeans to lock the instrument in any desired position fourth, to preventwater from entering the opening in the barrier when the instrument is inuse; fifth, to cover the opening in the barrier and to lock the cover inplace when the instrument is removed from the opening in the barrier.

I attain these objects by the construction illustrated in theaccompanying drawings, showing a preferred form of my invention in whicha ball on the tube of an optical instrument operates in conjunction witha socket member on a barrier, and in which:

Figure 1,represents a sectional elevation through the opening in thebarrier-instrument in operative position. Fig. 2,represents a sectionalelevation through the opening in the barrier,instrument removed, coverover opening closed. Fig. 3,-represents a bottom or plan view of thebearing socket inverted. Fig. 4,--represents a transverse sectionthrough the bearing socket, and locking plates. Fig. 5,represents anelevation of the lock for securing the bearing socket, releasing handleshown. Fig. 6, represents modifications of cover and clamp. Figs. 7 and8 represent modifications of socket and flexible cover.

Similar numerals refer to similar parts throughout the several views.

eferring to the drawings, a hollow segmental ball 1 is applied to thetube 2 of an optical instrument. This ball may be integrally fixed onthe tube or it may be slidablv connected therewith, being secured inposition by a set screw 3 in the collar 1 r of the ball.

A hollow socket 5, the bearing surfaces of which are concentric with thecurvature of the ball 1 and register therewith is hinged or otherwiseconnected to the barrier 6 adjacent to the opening -7. The walls of thesocket 5 are cut out, divided, or made separable as at 8 F ig. 3, toallow the instrument tube to be inserted into its operative positionwith reference to said socket. The socket 5 is held in positionwithrespect to the barrier, or released therefrom by a movable catch 9,which is provided with spring noses 25, projecting under the edges ofthe socket 5. The noses may be pushed back to release the socket by thecross bar or handle 26, connecting them.

Locking plates 10, the inner edges 11 of which are concentric with theinstrument tube and knurled or otherwise treated so as to provide anon-slipping contact with said tube, are arranged to move laterally inguides on the socket 5. This movement of the locking plates iscontrolled by the studs 13 set in the socket and projecting throughslots 14 in the locking plates. ing nuts 15 on the studs 13 secure thelocking plates in place.

ater is prevented from entering the opening 7 in the barrier, when theinstrument is in operative position therein, by the flexible cover 16,the center of which is cut out so as to make elastic frictionalengagement with the tube 2 of the instrument, while the outer edge issecured to a coaming 17 surrounding the opening in the barrier.

When the instrument is removed from its operative position upon thebarrier, the opening 7, in said barrier 6, is closed by a cover 18,which is provided with a strip of yielding material 19 adapted to bearon the coaming 17 surrounding the opening in the barrier when the coveris closed. This cover is held in close contact with coaming 17 by aclamp 20, a finger 27 on which engages a projection 28 on the socket 5,said clamp, which operates on a threaded member 22, connected with thecover, is maintained against said socket by a wing nut 21. An elongatedhole 23 in the male portion of the cover hinge 24:, if a hinge is used,permits the compression of the yielding strip 19 on the coaming 17.

The operation is as follows: Vhen the opening in the barrier is closedas shown in Fig. 2, the instrument is stowed conveniently near theopening 7. To open the cover 18, the wing nut 21 is unscrewed slightlyfrom the threaded member 22, the clamp 20 slipped down out of engagementwith the socket 5, the threaded member 22 swinging into a verticalposition and the cover 18 pushed upwardly and backwardly until itassumes the position on top of the barrier indicated in Fig. 1. Thecatch 9 is next retracted until socket 5 is released; said socket willthen drop downwardly and clear of the barrier opening. The instrument isnext inserted in the opening 7 and pushed up through the flexible cover16, the lower edge of the ball 1, being held at a higher level than thetop edge of socket 5 when the socket is in operative position. Socket 5is then swung up, the instrument case being passed through the dividedportion of the socket as at 8. The catch 9 engages the socket when itreaches its operative position and secures it therein. The ball 1 isnext seated on the bearing surfaces of the socket. Observations with theinstrument may now be taken, those in a horizontal plane by rotating theball 1 in its bearing socket 5 about the vertical axis of theinstrument, and those in elevation and depression by rota tions aboutany horizontal axis of the instrument. Horizontal observations can beobtained at any point within three hundred and sixty degrees. Those inelevation and depression are restricted according to the structureadopted at the opening 7.

The flexible cover 16 is capable of adjusting itself to the movements ofthe tube 2 of the instrument. If it is desired to retain the instrumentin any fixed vertical position, the wing nuts 15 are loosened, thelocking plates 10 are pushed in until the knurled edges 11 thereonengage tube 2 of the instrument, and the wing nuts 15 retightened.

To remove the instrument from the opening in the barrier, the operationis the reverse of that described above. The locking plates 10, if theyhave been engaged with the tube 2 of the instrument should be releasedand pushed back, the socket 5 released by the catch 9 and swung down;the instrument removed from the opening 7 and the flexible cover 16 andthe socket 5 swung back to its horizontal position. The cover 18 is nextpulled down on the coaming 17 by the threaded member 22. The clamp 20 isslipped into engagement with the socket 5 and the wing nut 21 tightenedup against clamp 20, thereby drawing the yielding strip 19 on the cover1nto compressed contact with the coaming 17 around the opening in thebarrier.

The observation instrument rests on its bearing surfaces by its ownweight, being retained there by the operator by means of the handles 35.lVhen desired to secure the instrument in any one position the lockingplates 10 are' brought into use as described above. The bearing isdesigned to act as a steady rest for the operator.

Various changes can be made in the details of construction withoutdeparting from the spirit of my invention.

The cover 18 may be pivoted, or not, as desired, see Figs. 1 and 6. Theclamp 20 could engage an independent bridge member 32, across theopening of the barrier instead of the socket 5 as shoWn, see Fig. 6. Theclamp 20 could engage the cover by the threaded member, 22, beingconnected to a cross member spanning the opening in the barrier insteadof the reverse as shown, see Fig. 6. The socket bearing may be separatedand pivoted on each side and held in place by a stud 40, and a nut 29,connecting a flange on the side of the socket to the barrier instead ofon one side as shown, in order to allow the instrument to be inserted inthe opening of the barrier, see Figs. 7 and 8. The flexible cover 16,can be attached to a floating ring 30, bearing on a collar 31, on theinstrument tube as in Fig. 7. There- 100 fore, in view of the abovemodifications, I do not desire to be strictly limited to the detailsshown.
